Apply Components

BAND-FRONT





Hydraulic pressure is applied to the front side of the front servo.
- This pressure causes the servo to stroke and apply force to the band.
- This action causes the front brake and coast clutch drum to be held.
- The front band holds the front brake and coast clutch drum to the case in 2nd and 5th gears.
- This causes the front sun gear to be held stationary through the coast clutch adapter and the front brake and coast clutch drum.

BAND-LOW/REVERSE





Hydraulic pressure is applied to the front side of the low/reverse servo.
- This pressure causes the servo to stroke and apply force to the low/reverse band.
- This action causes the low/reverse brake drum to be held.
- The low/reverse band holds the low/reverse brake to the case in 1st position and reverse gears
- This causes the low/reverse planetary assembly to be held stationary.

BAND-INTERMEDIATE

Part 1 Of 2:




Part 2 Of 2:





Hydraulic pressure is applied to the front side of the intermediate servo.
- This pressure causes the servo to stroke and apply force to the intermediate band.
- This action causes the intermediate brake and direct clutch drum to be held.
- The intermediate band holds the intermediate brake and direct clutch drum to the case in 3rd gear.
- This causes the input shell and forward sun gear to be held stationary.

CLUTCH-DIRECT





The direct clutch is a multi-disc clutch made up of steel and friction plates.
- The direct clutch is applied with hydraulic pressure and disengaged by return springs and the exhaust of the hydraulic pressure
- It is housed in the intermediate brake and direct clutch drum.
- In drive, the direct clutch is applied and coupled to the forward clutch, this drives the input shell and forward sun gear in 4th and 5th gears.
- In reverse, the direct clutch is applied and coupled to the input shell and forward sun gear.
- This action causes the forward sun gear to drive the pinions of the low/reverse planetary carrier.
- Since the low/reverse planetary carrier is held stationary by the low/reverse band, the pinions drive the output shaft ring gear in reverse.

CLUTCH-FORWARD





The forward clutch is a multi-disc clutch made up of steel and friction plates.
- The forward clutch is applied with hydraulic pressure and disengaged lay return springs and the exhaust of the hydraulic pressure.
- The forward clutch is applied in all forward gears.
- When applied, the forward clutch provides a direct mechanical coupling between the input shaft and the forward ring gear and hub.

CLUTCH-COAST





The coast clutch is a multi-disc clutch made up of steel and friction plates.
- The coast clutch is applied with hydraulic pressure and disengaged by return springs and the exhaust of the hydraulic pressure.
- The coast clutch is housed in the front brake and coast clutch drum.
- The coast clutch is applied when the Transmission Control Switch (TCS) switch is on and 5th gear operation is inhibited.
- The Coast clutch is hydraulically applied when the -transmission is in 2nd and 1st position.
- When applied, the coast clutch locks the input shaft to the front planetary carrier, thus preventing the one-way clutch from overrunning when the vehicle is coasting.
- This allows the use of engine compression to help slow the vehicle and provide engine braking.

ONE-WAY CLUTCH-FRONT





The front one-way clutch is a spray-type one-way clutch that is pressed into the center shaft.
- The front one-way clutch is driven by the ring gear of the front planetary carrier.
- The front one-way clutch holds and drives the outer splines of the center shaft in 1st, 2nd, 3rd, 4th and reverse gears.
- The front one-way clutch overruns during all coast operations and at all times in 5th gear.

ONE-WAY CLUTCH-LOW/REVERSE





The low/reverse one-way clutch is a spray type one-way clutch.
- The low/reverse one-way clutch holds the low/reverse brake drum and low/reverse planetary assembly to the case in 1st gear only.
- In all other gears the low/reverse one-way clutch overruns.
